Profile: Kempbio, Inc. specializes in providing baculoviral and mammalian expression systems. We provide GLP cell banking services. Cell banks from 50 to 500 vials which are prepared using optimized protocols to ensure high viability on breakout and vial to vial consistency. We produce cell banks for non-recombinant and recombinant mammalian & insect cell lines. Each bank is tested for mycoplasma contamination, sterility and viability on thaw. Time to confluency data is also collected for attachment dependent cell lines. A complete and comprehensive batch record is generated for each cell bank. We develop a robust system for the transient expression of recombinant proteins using the human cell line. This system provides a mechanism for the rapid expression of milligram to gram quantities of recombinant proteins with authentic human post-translational processing.
